Yuan Tiangang was telling the truth. Before the Tang Dynasty, some Taoist priests who made alchemy accidentally made black gunpowder when making alchemy, which was recorded as a fast-burning thing. However, out of selfish motives, these people did not refine it themselves.
The method of making black gunpowder was recorded, otherwise Yuan Tiangang would not have to test it over and over again.
Seeing that something he had been trying for half a month but couldn't figure out was actually done by a young man, Yuan Tiangang was so excited.
The old Taoist grabbed Du He's sleeve and said reluctantly: "Du He...it turns out that you are the second son of Prime Minister Du. Today, if you don't tell me the method of refining the raw materials of this elixir of immortality, I will
I won’t let you go.”
When Lu Bu saw this, he stepped forward to teach the old man a lesson.
Du He waved his hand and asked Lu Bu to go and guard the door first.
Du He sat down on the stone next to him, chuckled, and said, "Master Yuan, actually, I came to you today just because you stayed in the courtyard next to my Duke's Mansion in Lai!"
Yuan Tiangang shook his head hastily: "That won't work. That's my Yuan family's old house. I can't sell it to you for anything, otherwise my Yuan family will have no foundation."
Du He flicked his sleeves: "You are an old man. You are childless and alone. How can you talk about the foundation of the Yuan family? You are really amusing me to death."
"you……"
The Yuan family was so depressed that their faces turned red, but they couldn't say a word.
Seeing this, Du He stood up and said, "It seems that Master Yuan doesn't want to sell the yard, so forget it. Let's talk about it another day!"
With that said, Du He walked out.
Yuan Tiangang became anxious as soon as he saw it. He rushed forward to stop him and said anxiously: "Okay, I can sell the house to you, but you must tell me the method of refining the raw materials of the elixir of immortality."
Du He suddenly smiled and nodded: "Okay! But let's settle the affairs of the house first."
"You kid...you're still worried that I, Old Yuan, can't lie. Come on, I'll write you a document right now."
Yuan Tiangang was even more anxious than Du He, so he hurriedly asked the young Taoist priest Qingfeng to bring a pen and paper, and wrote a document for the sale of the house, agreeing that the sale price would be 500 taels.
Du He also visited the Yuan family's old house. It was quite large in area, well-equipped with buildings, and easily worth more than 1,000 taels.
Who knows, one second ago Yuan Tiangang kept saying that it was the Yuan family's old house and the foundation of the Yuan family, but in the blink of an eye, it was sold at a low price.
Is this old man going crazy while refining alchemy?
Du He also pressed his fingerprints and put the receipt away: "Early tomorrow morning, I will have someone deliver 500 taels of silver."
Yuan Tiangang waved his hands nonchalantly: "It doesn't matter, let's talk about alchemy first..."
Before he finished speaking, he was interrupted by Du He: "Yes, yes, stop it first. This thing is called black gunpowder, and it is not a raw material for alchemy. Not only will it not lead to immortality, it may even kill someone if you eat it."
"Don't worry so much, just tell me the recipe." Yuan Tiangang didn't listen to a word he said.
Du He had no choice but to pick up a piece of paper and write down the black powder formula.
Simply put, it is monosulfide, dinitrate, and charcoal. All primary school students know that, of course, this is a weight ratio, not a volume ratio. For example, the primitive firecracker that Du He just made casually, because there is no weighing tool, it is just configured according to feeling, so
The effect of the explosion is not very ideal.
As if he had found a treasure, Yuan Tiangang put the formula away and began to drive people away: "Seeing that it is getting late, Mr. Du, please come back quickly, otherwise the city gate will be closed later and the curfew will begin."
Du He was very speechless.
This guy was so enthusiastic a moment ago, but after getting the formula, he started to turn against anyone else.
Helpless, he could only take Lu Bu and quickly return home.
…
Seeing that the sun has set, darkness gradually engulfs the earth.
At the back door of Laiguo Palace, several figures appeared.
There were five people in total, all wearing black shorts and hats.
The leader was none other than Changsun Chong.
Changsun Chong said to his four men: "The back door will be opened later. You can follow me in to arrest people. Du He's room is directly opposite the back door. I am very familiar with Du Mansion. There are no servants at all at this time.
Once you catch someone, knock him out immediately and take him away! You must do it quietly and never be discovered."
A man in black asked curiously: "Master, what happens after you take the person away?"
Changsun Chong suddenly laughed obscenely: "Hehe... if you catch Du He, strip him naked and throw him on the street. Wait until Marquis Wu who patrols the city finds out. Tomorrow, he will become famous in Chang'an City."
"Hahaha……"
Several people laughed obscenely.
Changsun Chong used to have a close relationship with Du He, so he was very familiar with Du's mansion, otherwise he would not have dared to quietly bring people to arrest him.
This time, Changsun Chong believed that he was foolproof. As long as he could handle this matter beautifully, he would be able to make a great contribution in front of the prince.
Several people were so carried away that they did not notice that a fist suddenly appeared behind Chang Sun Chong and hit him on the back of the head.
boom.
Changsun Chong rolled his eyes and fainted to the ground.
Before the four men in black could react, they were knocked unconscious.
Under the dim light, Lu Bu easily arranged the five people neatly, then walked up to Du He and said, "Master, it has been solved. No one found out that we did it."
Du He stepped forward, looked at Changsun Chong, and couldn't help but kick him: "What a coincidence? You dare to come to Laiguo Duke's house to catch someone, and you want to ruin my reputation."
Lu Bu asked: "Master, what should I do?"
Du He rolled his eyes and suddenly smiled: "Since Changsun Chong wants to be famous, I have to satisfy his injustice..."
As he spoke, Du He leaned into Lu Bu's ear and whispered some arrangements.
Lu Bu nodded.
Later, Du He returned to the mansion alone, had dinner, and then returned to his room.
At a quarter of the hour, Lu Bu came to the window, knocked on the window, and whispered: "Master, everything is done."
Du He nodded with satisfaction, blew out the candles, and went to bed.
"The stage is set up, the actors are in place, and we're just waiting for a good show tomorrow..."
Du He said to himself.
A night of silence.
…
The next day, the fifth watch.
The watchman carrying a lantern was walking on the streets near Pingkangfang.
Not far away is the towering Imperial City, brightly lit.
Suddenly, the watchman stared at the wall in front of him for a moment.
I saw nothing but white flowers lying there.
"Could it be that the sheep that were slaughtered by some family fell off?"
The watchman stepped forward curiously.
After walking a few steps, he suddenly let out a loud scream and ran away as fast as he could.
Because what was on the ground were not slaughtered and stripped sheep, but several stripped men, five in total, naked, hugging each other.
Not long after, Marquis Wu, who was patrolling the city, arrived.
There are a large number of Wu Hous in Chang'an City, who are responsible for patrolling the city after the curfew. However, this place is located below the Imperial City, so Wu Hous generally do not patrol here. Who would have thought that such a jaw-dropping scene would appear.
